NITED STATES THADDEUS M. HALL, OF CAMERON, MISSOURI, ASSIGNOR OF ONE-HALF TO WILLIAM MGGALLUM, OF SAME PLACE.

DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 259,272, dated June 6, 1882.

Application filed March 23, 1882. (No model.)

To all whom it may concern:

Be it known that I, THADDEUS M. HALL, a citizen of the United States, and resident of Cameron, in the county of Clinton and State of Missouri, have invented a new and valuable Improvement in Railroad Dumping-Oars; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part ofthis specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side View of my railroad dumping-car. Fig. 2 is a top or plan view, and Figs. 3 and 4 are cross-sectional views of the same.

This invention has relation to dumping-cars; and it consists in the construction and novel arrangement, in connection with the under framing supported in the axles, of the transverse end beams, the central longitudinal platform connected thereto, the lateral beams extending parallel to the platform and pivoted to bearings in the end beams, and the dumpingboxes firmly secured to said lateral beams, all as hereinafter set forth.

In the accompanying drawings, the letter A indicates the under framing, hiniug bearings for the car-axles B. G 0 represent transverse beams connecting the longitudinal beams of the under framing and extending above the wheels D. Arms E of said beams extend over the wheels, and bearings a are provided in the beams near their upper surfaces to receive the journals 1) of the lateral rock-beams F. These rock-beams are squared, and carry the dumping-boxes G, which are firmly bolted to the middle portions thereof. The dumping-boxes are formed with backs c and ends d, and when they are in position for loading their back portions are adjacent to each other and bear on the longitudinal middle platform, H, which is let into the transverse beams and firmly bolted thereto. This middle platform lies between the lateral rock-beams F, and the upper surfaces of the latter are on the same level with the top of the platform. The bearings a for the journals of the rock-beams are usually slots,

as shown in the drawings, and are provided with vertical pins 0, which separate the outermost portions of the slots and serve to keep the rock-beams and their dumping-boxes, when loaded, sufficiently apart to afford a walk on the middle platform, between the boxes, from end to end of the car.

In dumping the boxes G are designed to reverse themselves, turning completely over, so that their bottom surfaces are uppermost. The rock-beams are also reversed, and form, with the middle platform, a fiat surface, on which some classes of freight can be readily loaded. When the rock-beams are reversed the pins e are removed from the bearings aand thejournals pushed to the inner ends of the bearings, thus shifting the boxes toward each other under the middleplatform and between the wheels on each side. In this position the boxes engage and are supported by low bearing-bars L, forming a part of the under framing.

A car having pivoted dum ping-sections capable of being discharged, one at the center and the other at the side of the car, is not new, and is not broadly claimed herein.

Having described this invention, what I claim, and desire to secure by Letters Patent,

1. A dumping-car having the transverse end beams, O, the middle longitudinal platform, H, connected thereto, the lateral reversible rockbeams F, extending parallel to the platform and pivoted to hearings in the end beams, and the reversible dumping-boxes G, firmly bolted to the lateral rock-beams, substantially as specified.

2. A dumping-car having a middle platform and reversible rock-beams and dumping-boxes, and convertible into a flat car, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

THADDEUS M. HALL.
